I really like this show so far, it's fun and focused on its goals while giving little tidbits of mystery regarding what's happened in the past several years. I like the new characters, Towa feels balanced as a knightly-but-still-goofy protagonist, and Moroha is based I love her. Setsuna isn't my favorite character type but I'm still interested in her arc.
Admittedly I was taken out of the episode (I believe it was 2 or 3) when Moroha was used as an exposition talking head in the background of a fight, but at least it didn't stop the action. I appreciate that, this show doesn't seem to stall on unimportant things and finds ways to shove exposition dumps into ongoing plot.
